Application lcdJuly 23, 1921. Serial No. 486,986.

'le it known that l, ERNST G. LANGE, a citizen ol the United States ofAmerica, residing at Detroit, in the county of Wayne and State oiMichigan, have invented certain new and use'iul Improvements in WindowFasteners; and l do hereby declare the following to be a iull, clear,and exact description oit the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a window fastener,` and is particularlyconcerned with improvements in structure shown in my prior applicationtor patent relating to the same matter. In the present invention. theconstruction has been greatly simplified thereby reducing the cost oitmanufacture, and the action is more positive, both window sasbes beingpositively held against movement in either direction when once fastenedin position. lt is an object and purpose ot the present invention toconstruct the lock in the simplest manner possible consistent with theeffective attainment of the ends above outlined, and so design thefastener that tools and dies needed will be reduced to a minimum, manyparts being duplicated iu theV assembly, whereby a Very economicalconstruction is produced yet one which is particularly practical,durable and ci'lii-ient 'tor the locking ot windows either in closed orpartly open posit-ions.

lF or an understanding ot the invention and thc constructions used inembodying the saine. reference may be had to the following description,taken in connection with the accompanying drawing, in which,

Fig. 1 is a perspective view, showing my window tasteuer applied to awindow.

Fig. .2 is a` horizontal section through the Hll'llC.

Fig. 3 is a vertical section through the tastei'ier and adjacentportions oiz the window sashcs` with which it is associated, the sectionthrough the 'fastener being on the plane ot line 3-8, ot' Fig. 2. and

Fig. 4f is a fragmentary perspective view,

showing the manner of attaching the pinl guides to the base plate in thefastener.

trike reference characters reiger to like parts in the different ligureso't the drawing. This invention' is particularly adapted for use withvertically sliding windows. ltn Fig. 1 the upper sash 1 and lower sash 2are shown mounted for vertical sliding move ments in a window iframe orcasing @n the inner side of the casing a bar otl Hat metal t ispermanently secured, the same being 'formed with a plurality o1Eopenings 5 therein located vertically one over the other in spaced apartrelation. Likewise, a. similar bar 4a having like openings 5 therein ispermanently attached to the side 6 ot the upper sash.

On the upper side 7 of the lower sash 2 of the window, a tas-tener :toruse in conjunction with the two bars l and 4a is secured` Inconstruction, the same includes a base plate 8, which extends beyond theedge of' the sash member 7, is then turned downwardly and back towardthe sash member, as indicated at 9, and thence bent downwardly to Jforma section 1,0 which lies against the inner side ol" the sash member 7.The base is secured in Xed relation to the lower sash by means ot screws11 and 12 passing through the base 8 and the section 10 thereof into themember 7, as fully shown in F ig. l.

rTwo inverted U-shaped guides 13 and 11i are located above the base 8and are secured thereto by means oit' tangs 15 on the sides of saidguides passing' through openings 16 in the base and heai'led over on theunder side ot the base. These guii'les are located at right angles toeach other, one adjacent one side edge oil the base and the otheradjacent lhe inner end thereol. Each guide, in its upper side is formedwith a slot 17. The guides are duplicates and can be made with the samedie.

Locking pins 15% and 2O are slidably mounted in the guides 13 and, 14,and are provided with small pins 19 and 21. respectively, which extendupwardly through the slots 17 in vthe guides. The pin 18 is adapted toenter the openings 5 in the bar et ou the upper sash. while pin Q0 isadapted to enter the similar openings 5 in the bar i on the casing 3when the pins are extended beyond the base. l

On a pivot stud 22 fixed to and extending upwardly from the base 8, abell-crank lever is pivotally mounted having two arms 23 and 224i-, .inthe tree end ot the former ot which a slot 25` is cut for the receptionof the pin 19. The other arm 24 has a closed slot 26 through which thepin 21 passes, the arm extending beyond the pin and over the edge Zilliol the base and being t'ormed at its end with a down-turned lip 27. Acoiled tension spring 28 is attached at one end to `arm 23 and at itsother end to the base S, the normal effect oit which is to turn thebell-crank lever and operate both. locking pins 18 and 2O to outerposition, shown in Fig. 2. By pressing against the lip 27, the lever'may be moved against the torce exerted by the spring, and bothlocking.,r pins simultaneously retracted.

The bcllfcrank lever, locking pins and guides therefor are covered *byra .housing having` an upper top 29 and depending sides 30 in the one otwhith arm 24 passes through a portion is cut away to leave an opening`31, permitting;` the movement ot the arm as needed ,tor the operation ofthe bell-crank lever. 'lhehcuising` is secured to the.base

bv a rivet 32 passing through the base and top olf the housing as shown.Vl prefer to make the housing so that it does not cover 'the entirebase, thereby leaving anv exposed 'portion throughifwhich the screw llmay be passed.

i locking` pins are normally projected to seat l crank lever The uppersash is firmly held in openings 5 in thebars 4 and 4", thereby locking`the lower sash to the casingV and the upper sash to the lower sash, thepins being simultaneously withdrawn whenever the position oi the saslieswith respect to each is to be changed or the sashes are to be changed ywith respect Ato the casing. This operation is very readily accomplishedby merely pressingr on the end oli lthe arm 24 of the bell I agrainstmovement with respect to the lower t sash :n lboth directions when thepin 18 1s tiov 'from the outside.

rlhe ctmstruction is economical to manu- 'laeturc as all of the partsare {simpleysheet metal tru-nis. very readily cut and formed at oneoiieration except. possibly, the base, and this requires but littleadditional 'forme intr atter blanling is done. YThe bars 4 and 4a aresubstantial duplicates, andthe locking pin guides 13 andl4 areduplicates, re-y vquiring` but one die forfthe production of both.l Thelock is very durable, as Well as Vith this construction ot fastened thevsecurely locked lever pivotally vmounted on the'base having two arms?one being slotted at its free end 'for he reception of one oi' saidoperating pins, and the other havinga slot between its ends 'iniwhichthe other operating; pin extends7 said lastn're'ntioned arm being eX-tended beyond the base and'iormed with a ydown-tinfned lip at one edge74substantially as y described;

2'. A construction containing the elements in combination defined inclaim l, combined with'` a housing` attached to the base and coveringthe'guidesllocking pins and lever, said housiiii lat loner side havingyan opening throi which the second mentioned arm of ythe lever extends,and ha ving other openings in other sides 'for the locking` pins,substantially as described.

3. A. latch for windows comprising a base plate adapted to be positionedhorizontally and formed at one end with `a reversely turnedanddownwardly and inwardly eX- tending portion terminating in a downvHardly extending' vertical vportion through which securingmeans areadapted to pass to secure the plate to a window sash, two locking pinsslidably mounted at right angles to each other on the base, the outerends ol the pins beingv adapted `to project beyond the edges 'oit thebase, and an operating member pivotally mounted on the base and havingoperative connection with both pins 'tor siuitiltaiieously oliieratingvthe same in ward or cuitward,r substi'intially as described.

4. VA latch Ytpr windows, comprising,r a base plate. Atwo U-shapedguides securedv in inverted yposition on the upper side ofi the baseplateat right angles to each other, locking pinssllidably mounted underthe guides, a. hell crank .lever pivotally mounted on the base havingarms, one for each pin operatively eonnerted therewith to simultaneouslyslide the pins on pivotal movement of the lever-'hand means tor,manually turning the lever about its pivot.' substantially as describedIn testimony whereof I aiiix my signature.
